' VEHICLE-WHEEL RIM.

To all whomtt may concern:

Be it known that 1, WILLIAM N. BOOTH,

a citizen of the United States of America,

residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Veicicle-Wheel Rims, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle wheel rims designed for use as demountable rims, and has particular reference to that type in which'the rims are split transversely to permit of collapsing in diameter for engagement with the tire casings. Rims of this character are detachably secured to the felly rim of the wheel in various ways, as by clamping or clamping and wedging; usually the felly band is provided with a flange on its innerside upon which one edge of the demountable ,rim seats, and clamping lugs upon the opposite side serve to retain .the rim against this seat. If, in addition to clamping, there is a wedging action of'the lugs, a tension will be placed upon the split rim, which will tend to separate the ends thereof, and it is one of the objects of the present invention to provide means for preventing such separation. On the other hand, if the rim is secured by merely olamping its outer edge, there will nevertheless be a tendency for it to be forced upward upon the inclined seat of the felly body flange, which will separate or tend to separate the endsof the demountable rim upon that side of the wheel. Another feature of my invention is the means employed for preventing such separation and the invention further comprises various novel features as hereinafter set forth. In the drawings:

Fig. 2 is a cross section thereof;

Renewed September 10, 1919. Serial No. 322,982.

Fig. 5 is a perspective view of the clampmg lug. v 3

A is the wheel felly, and B the felly rim mounted thereon, which isfprovided with the flange C at the inner side thereof inclining upward and outward to form a seat for one edge of the demountable rim D. Thls rim is transversely split at E and the engaging ends thereof on opposite sides of the split are preferably provided with alinmg means, such as the tapering lug F on the one engaging a corresponding tapering recess G in the other.

When the demountable rim is first placed upon the folly rim the ends will beheld together by the tire, but if the rim were wedged upward upon the inclined seat C, ,these ends might be forced apart. To prevent such a result I have provided interlocking shoulders on each end of the split rim and upon the flange. at one side thereof,

the demountable rim D along the line H and striking the metal outward to form a square shoulder 1.. The flange C is also apertured at J and J to receive the struck out portions I and to provide an opposed shoulder J preventing longitudinal movement. Thus when tension is placed upon the demountable rim b wedging it tightly upon the seat flan e C the engagement of the shoulders I with the shoulders J will prevent any separation of the rim ends. To

facilitate the initial engagement of. the

shoulders I with the apertures J and J, the latter are so fashioned as to form an enlarged entrance slot with inclined edge portions J 3 which guide the shoulders I into engagement with the shoulders J These entrance slots are in a portion of the flange C which is of lesser diameter than the inably byshearing slightly into the ottom' portion D of the demountable rim and striking that portion downward. Thus the portions of the cooperating shoulders I and resist expansion, 'The inclined guide which are in final engagement with each [other when expansive force is placed upon the rim will. be parallel to each other and transverse to the rim, so 'as to effectively portion J I initially engaged by H the downwardly-extending portion I will have been passed by the latter and the square shouldered portions engaged,

The construction as thus far-described is t all that is required to hold the ends'of the in position, this will exert an expensive" force on the outer edge of the rim which will not be successfully reslsted by the engagement of the shoulders I and J Such a result, I have prevented by arranging one of the wedge lugs K so as to overlap the split in the outer edge of the rim, and have provided this lug with locking shoulders for engaging cooperating shoulders in the outer flange of the demountable rim. As shown, the beaded portion L of the outer demountable rim flange is notched at M fictions and M on opposite sides of the split, and

the 111 K is ormed with projecting portions and K? for engaging said notches.

The lug K is also'provided with the usual wedge portion K for bearing against the under face of the rim D, and with an a ertured downwardly -extend1ng portion on ages the clamping bolt.

1th he construction last described, when the demountable rim is in position and ready to be clamped and wedged, the lug K which registers with the split in the rim is tightened and by forcing the proand K into the notches M and will lock the outer edge portions of the demountable rim from separation at the split. l he other wed e lugs may then be tightened to clamp t e demountable rim firmly upon thewheel, but this action can have no efiect in separating the ends ofithe rim, as these are locked on both the inside and outside edges thereof.

What I claim as my inventionis: L'The. combination with a transverselysplit demountable rim having a tire-retaining flange ,at the side thereof, of portions struck out from said flange to form 9 posed shoulders on'opposite sides of the split, and

a felly member having a seat for said 'rim, provided with cooperating shoulders for engaging and locking said opposed shoulders from separation.

2. The combination with a transverselysplit demountable rim having a tire-retaining flange on its inner edge, of a felly band 4 which able rim for interlocking with the opposed provided with an inclined flange forming a seat for the inner side of said demountable rim, struck-out lugs on the flange of said demountable rim upon opposite sldes of the 'split therein forming opposed shoulders, and cooperating shoulders on the seat flange ofthe felly band. formed by cutting away portions thereof. ,1

.3. The combination with atransverselysplit demountable rim having .a tire-retaining flange on itsinner side, of a felly band provided on its inner side with an inclined flange forming a seat for said demountable rim, said band being provided with cutaway portions on oppos te sides of the split in the demountable rim, and opposed $110111",

ders on said demountable rim on opposite sides of the split thereof formed by portions struck outward from said tire-retaining flange, said shoulders being adapted to engage the apertures in' said seat flange and to Interlock with opposed shoulders formed by the edges thereof. 1

4. The combination with a transversely- I .its inner edge .forming a seat for said demountable rim, said flange being cut away to form opposed shoulders on opposite sides of the split in the demountable rim and inside'of the seat bearing therefor, said outaway portions being enlarged inside of said seat bearing to form entrance slots with inclined edge-flanges, and opposed shoulders struck out from the flange of the demount:

shoulders formed by the edges of said apertures, said'struck-out portions having'downward extensions which initially engage the enlarged entrance slots in said seat flange' to guide the cooperating shoulders into engagement.

5. The combination with a transverselysplit demountable rim having tire-retaining flanges. on its inner and outer edges, of a felly band havin an inclined flange form.-

ing'a seat for t e inner edge of said de- 1 mountable rlm, wedge clamping lugs for the outer ed e of said demountable rim, interlocking s qulders formed on the inner tire flange of said demountable rim and upon s'aid'felly band seat flange on opposite sides of the split in the demountable rim, and interlocking shoulders formed on the outer edge of said demountable rim on opposite sides of the split and in one ofthe clamping lugs.

e. The combination with a] transverselysplit demountable rimiijhaying struck out a portions on opposite'sides of the split forming opposed shoulders, ofia felly member havinga seat for said demountable rim and cooperating shoulders for engaging and locking said opposed shoulders from separation.

7. The combination with a transverselysplit. demountable rim having a tire-retaining flange at the side thereof, of shoulders on said flange on opposite sides of the split, and a felly member having a seat for said demountable rim and cooperating shoulders for engaging and locking said first-mentioned shoulders from separation.

In testimony whereof I aifix my signature in the presence of two witnesses.
